A tribute to jim simons in celebration of the importance of basic science and mathematics.
Leaders in mathematics, science and philanthropy gathered on June 27, 2025, to remember the incredible contributions of Jim Simons and to inspire continued philanthropic support of basic research.
In a cosmic first, scientists watched planet-forming materials begin to solidify around a newborn star, offering a peek into what our Solar System may have looked like at birth. It’s a stunning replay of planetary evolution, just 1300 light-years away.
This Review summarizes the current knowledge on mortality-defining toxicities of chimeric antigen receptor T cell therapies beyond cytokine-release syndrome and immune effector cell-associated neurotoxicity syndrome. The authors discuss underlying mechanisms and how these affect timing and management, and outline key unmet needs and future priorities.
Physicists have detected the biggest ever merger of colliding black holes. The discovery has major implications for researchers’ understanding of how such bodies grow in the Universe.
“It’s super exciting,” says Priyamvada Natarajan, a theoretical astrophysicist at Yale University in New Haven, Connecticut, who was not involved in the research. The merger was between black holes with masses too big for physicists to easily explain. “We’re seeing these forbidden high-mass black holes,” she says.
The discovery was made by the Laser Interferometer Gravitational-Wave Observatory (LIGO), a facility involving two detectors in the United States. It comes at a time when US funding for gravitational-wave detection faces devastating cuts. The results, released as a preprint on the arXiv server1, were presented at the GR-Amaldi gravitational-waves meeting in Glasgow, UK, on 14 July.
Degradation of proteostasis, mitochondrial function, and cellular stress resistance results in a build-up of damaged proteins, oxidative insult, and chronic inflammation, characteristic of aging. CHIP is essential for maintaining protein quality control and cellular homeostasis by having dual E3 ubiquitin ligase and co-chaperone activities. CHIP facilitates proteostasis by maintaining proteostasis in misfolded, aggregated proteins by promoting their degradation. Mitochondrial dysfunction, oxidative imbalance, and cellular senescence are caused by its age-associated decline and contribute to neurodegenerative, cardiovascular, and oncogenic disease pathogenesis. Examples of recent pharmacological and gene-based strategies to correct CHIP and restore stress resilience have been made.
A new study from Aarhus University turns our understanding of how running injuries occur upside down. The research project, which is the largest of its kind ever conducted, shows that running-related overuse injuries do not develop gradually over time, as previously assumed, but rather suddenly—often during a single training session. The research is published in the British Journal of Sports Medicine.
“Our study marks a paradigm shift in understanding the causes of running-related overuse injuries. We previously believed that injuries develop gradually over time, but it turns out that many injuries occur because runners make training errors in a single training session,” explains Associate Professor Rasmus Ø. Nielsen from the Department of Public Health at Aarhus University, who is the lead author of the study.
The study followed 5,205 runners from 87 countries over 18 months and shows that injury risk increases exponentially when runners increase their distance in a single training session compared to their longest run in the past 30 days. The longer the run becomes, the higher the injury risk.
